In DOS, the following line will generate a random number between 1 and 100. To get 0-100, remove the plus one at the end.
set /a num=%random% %%100 +1
The control variables.
An independent variable can be changed itself and does not vary if other items around it are changed. A dependant variable changes it value in response to changes in other items.
A constant value cannot be changed once set. A variable can be changed whenever you want.
Constant variables refers to those variables whose values cannot be changed. These variables should be initialized along with their declaration. Attempt to change the value of a constant variable will generate compile error. The syntax for declaring a constant variable is:const data-type variableName = value;
A static variable is one which is not stored on the stack but in the memory of the program. Static variables can be changed.
a changed variable is something that you have changed
Sure. If you can observe that when variable A changed, variable B didn't change, and this happens repeatedly, that is a good indication that there is no relationship between those variables.
In scientific experiments, the variables may be changed.
control variables: the things that are not changing.Independent variables: the things that you change.Dependent variables: the things that are changed due to the independent variable
The controlled variables.
The controlled variable is the type of soybean, and the changed variable is the type of water that the soybean is absorbing.
Yes. In fact, in multiple regression, that is often part of the analysis. You can add or remove independent variables to the model so as to get the best fit between what values are observed for the dependent variable and what the model predicts for the given set of independent variables.
